As todayâ€™s tall buildings become ever taller and more slender, wind-induced vibration is a serious design issue.Installing tuned mass dampers (TMDs) is a reliable solution to mitigate wind-induced vibration of tall buildings. This paper investigates structural performance of vertically distributed multiple TMDs along the height of the building. Compared with the conventional TMD system, composed of very large TMD masses installed near the top of the building, much smaller TMD masses are used in the vertically distributed TMD system.Though the performance of the vertically distributed TMD masses is somewhat reduced,the system can still be very effective depending on the range of the distribution. In addition,the valuable spaces near the top of tall buildings can be saved for more desirable architectural functions.
